To uit iii/rom it may concern Be it known that l, Jol-ru KELLY, a citizen ot the United States, residing at Chicago, in the county of Cook and State otl lillinois, have invented a new and useful lmproveinei'it in Deinountable Wheels. of which the following is a specification.

My object is to provide novel and simple moans tor rcleasably securing a vehicle wheel. in position on a member adapted to rotate with the wheel, which will operate to securely hold lthe wheel to said rotary niembei', and which will permit the wheel to be readily removed and replaced, or another substituted thereor.

leterring to 'the accompanying draw ings---ligure Il is a view in sectional elevation the central portion or' a wheel, and the support therefor, constructed in accord ance with my invention, the section being taken atthe line 1 on Fig. 2, and viewed in `the direction ot' the arrow. Fig. 2 is a section taken at the line 2 on Fig'. 1, and viewed in the direction ot the arrow. Fig. 3 is a view in elevation ot one of the similar plungers employed for holding the wheel .to the rotatable member on which it is directly supported; and Fig. 4, a view in elevation of one ot the similar cam devices employed :tor coperation with the plungers.

l have chosen to illustrate my invention as applied to a wheel structure journaled on'an axle, which is the condition presented in the case of the front Wheel of an automobile, though it will be readily apparent `from the following that certain features of my invention are not limited to use in this particular connection.

@ne of the front steering wheel axles of an automobile is represented at 5, this axle carrying ball-races 6 and 7 between which and ball-races 8 and 9, carried by an inner hub 10, balls 11 are interposed, thus roviding ball-bearings between the inner ub 10 and` the non-rotary axle 5. The outer hub of the wheel is represented at 12, this hub being connected with the telly, not shown, through the medium of spokes 13, the telly, spokes and outer hub-section 12 being adapted'to be bodily removed from.

and replaced on the inner hub-section 10 as a unitary structure.

The inner hub section 10, in the preferred embodiment of my invention, contains, in its periphery, diametrically opposed radially extending socketsl, and is tapered toward its outer end, as indicated at 14. The` sockets 13 are provided for the reception of interlocking members carried by the outer hub-section 12 to cause the inner and` outer hub-sections described to rotate as a unitary structure.

The interlocking members, in the pre ferred construction illustrated, are in thc 'lorin of plungers 15 which slide in bosses 16 containing openings 17 which open through the inner surface of the hub-scction 12, the openings 17 being so disposed. that. they will register with the sockets 1B when the outer hub-section 12 is positioned on the inner hub-section 10, as represented in Figs. 1 and 2. The plungers l5 have stein portions 18 oi. reduced diameter which slide through openings 20 in plugs 2l screwed into the outer ends oi the openings 17 in the bosses 16, coiled springs 2%?, being confined between the heads of the planners 1,5 and the inner ends oi the plugs 21, und vieldngly forcing the heads oi? the 'plunger-s toward the center of the hub-section 12. The outer ends of the stems 18 are shouldered, as represented at 2l, at which shoulders the plungers bear against the ends ot the plugs 21, the latter being provided with cain-sur faces 25 upon which the shoulders 211 ride when the plungers are axially rotated, for moving the lutter radially in the openings 17.

lThe parts of the structure are so proportioned that the plungcrs 15, under the action of the springs 23, will be projected into the sockets 13 of the inner hub-section 10 when the parts are in the position il1ustrated in Figs. 1 and 2, the plungers operating to secure the outer hub-section 12 to the inner hub-section 10, so that these two parts will rotate as a unitary structure.

Assuming the parts to be in the positions illustrated in Figs. 1 and 2, the operator muy release the outer hub-section 12 from the inner' hub-section 10 by axially turning the plungers 15 which causes the shoulders 24 to 'ride upon the cam-surgases 25, thus withdrawing the heads of the plungers 15 from the sockets 13, the shoulders 24 seating upon the outer flat surfaces 26 of the plugs 21 which holds the plungers in retracted position. All of the plungers having been removed from the sockets 13, the outer hub-section 12 and the parts carried thereby are then removed from the inner hub-section 10 by sliding the hub-section 12 'longitudinallylof 'the' 'hubn section l0. iin assemblingthe same outer hub-section, or one to ,be'sulistitutedtheref for, with the inner hub-section 10., theouten hub-section may be rst slipped over 'the inner hub-section to telescope one `vvitli the.

as stated, and the louter hub-section l2 then y telescoped with the inner hub-section l0, the tapered surface 1li of the inner hub-section in the telescoping operation, by engaging with the tapered ends 27 of the plungers, causing them to belmoved radially outward, but as soon as the plungers register' with the sockets 13, the latter will be projected into them by the action of the springs 23.

While i have illustrated and described my invention as applied to a construction wherein the inner hub-section is rotatably mounted on a non-rotary axle, it Will be readily understood that my invention may be applied with advantage to structures, wherein the part to which the outer bubsection is connected is rigid on a shaft, or .a part oit tire latters and has a rotary move-y1 nient. Furthermore, ii do not Wish to be inria understood asintending to limit my inventionto any otberparticulars of the construction'sh'own, as 'the same may be variously modi-tied and altered Without departing "from the spirit of my invention, it being my intention to claim. my invention as broadly and completely as the prior state of the art n ported' on said member, a plunger on the v hub of said Wheel movable into and out of said socket for releasably lockingtogether ysaid Wheel and member and provided with.

"a stem, a spring tending tov project said plunger into said socket, a bearing member beyond said'plunger provided with an inclined face terminating in a stop' surface, and aprojection on saidstem adaptedA to ride against saidinclined surface and seat upon said stop surface upon rotating saidv stem,
